The C-Test: An Integrative Measure of Crystallized Intelligence
Journal of Intelligence, 2015 Crystallized intelligence is a pivotal broad ability factor in the major theories of intelligence including the Cattell-Horn-Carroll (CHC) model, the three-stratum model, and the extended Gf-Gc (fluid intelligence-crystallized intelligence) model and is ...

Age differences in fluid and crystallized intelligence
Acta Psychologica, 1967 Abstract The general purpose of this study was to describe differences in intellectual functioning associated with aging in adulthood. Estimates of broad factors identified as fluid intelligence, crystallized intelligence, general visualization, speediness, carefulness and fluency were obtained by combining scores on several tests found to define ...

Relative importance of college success predictors: fluid intelligence, crystallized intelligence, and grit [PDF]
Proceedings of the 3rd International Conference on Higher Education Advances, 2017 This study aimed to compare the predictive power of grit and two cognitive ability tests of fluid and crystallized intelligence used for university admission on the success of college students in Turkey. Utilizing Cattell’s Investment Theory and Ackerman’s PPIK Theory of Adult Intelligence, we hypothesized that knowledge tests would be a better ...

Gender differences on tests of crystallized intelligence
European Journal of Education and Psychology, 2015 This study aimed to determine whether performance on tests of crystallized intelligence is affected by gender and to ascertain whether differential item parameters could account for the gender disparities. The sample comprised 1.191 individuals (55% women) between the ages of 16 and 77 years old (M=22; SD=9.5).
